Description

Technical Field

[0001] This invention relates to a mechanism for seizing classified materials, specifically a highly secure, contactless mechanism that ensures the entire process of seizing classified materials is accurate, reliable, and free from leaks. This contactless secure mechanism can be installed on equipment such as classified material seizure cabinets, storage cabinets, and destruction machines. Background Technology

[0002] Because classified media (such as paper classified documents, CDs, USB flash drives, hard drives, etc. that store classified information) contain a large amount of classified information, the consequences of a leak would be extremely serious. Therefore, it is necessary to strictly control the people who come into contact with classified media, the scope of contact, and the degree of knowledge of them.

[0003] Currently, the management of classified materials is strictly enforced by designated personnel at specific times and locations. When classified materials need to be destroyed, they are delivered to the destruction center by designated personnel for registration, collection, and destruction; or, they are delivered to the classified materials destruction center by designated personnel for registration, collection, and destruction. Although the entire process is strictly carried out according to requirements, it involves at least three people, posing a risk of classified information being stolen or classified materials being swapped. For example, the person scanning the code to register the classified material may indeed be sending it for destruction, but the material actually delivered to the destruction center may not be the correct material, indicating a swap. Alternatively, the material delivered to the destruction center may indeed be the correct material, but during the delivery process, the person who handled it may have stolen the classified information or swapped it.

[0004] Therefore, it is necessary to mitigate risks through technological means. Summary of the Invention

[0005] In view of the above reasons, the purpose of this invention is to provide a contactless secure collection mechanism for classified materials. The custodian of the classified materials directly interacts with this secure collection mechanism, which completes the anti-fraud scanning registration and collection process directly within a fully enclosed space. This prevents the classified materials from being touched by others during the collection process and avoids the risk of the materials being swapped or classified information being stolen after scanning, collecting, and registering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a contactless classified carrier security collection mechanism, which includes a feeding box, a barcode scanning operation module, and a flip-plate unloading module; The feeding box is a box with an opening at the front. The top of the box has a feeding port that is only for classified carriers to pass through. Below the feeding port is an inwardly recessed cavity. When a classified carrier is fed into the feeding port, it falls backward into the inwardly recessed cavity under the action of gravity. The scanning operation module is movably installed at the opening of the feeding box, forming a closed space with the feeding box for containing confidential carriers; the scanning operation module has a built-in movable scanning module, which can be operated without contact to scan the QR code or barcode on the confidential carrier contained in the closed space. The flip-plate unloading module is fixed to the bottom of the feeding box. When the confidential carrier in the sealed space completes contactless scanning and is confirmed to be confiscated, the flip-plate unloading module opens, and the confidential carrier falls into the collection cabinet below the collection mechanism through the flip-plate unloading module.

[0007] Furthermore, the scanning operation module includes a front cover, a resistive touchscreen, a support frame, a transparent fixing plate, a scanning module, a stepper motor, an X-axis zeroing sensor, and a Y-axis zeroing sensor; the support frame is fixed to the front cover by screws, and the resistive touchscreen is clamped between the front cover and the support frame; the fixing plate is located behind and connected to the support frame; the stepper motor is fixed on the fixing plate, and the stepper motor drives the scanning module to move; the X-axis zeroing sensor and the Y-axis zeroing sensor for positioning are fixed on the fixing plate.

[0008] Furthermore, several sets of infrared receiving diodes are provided at the opening of the feeding box and inside the feeding box cavity; correspondingly, several sets of infrared light emitting diodes are provided on the scanning operation module; the infrared light emitting diodes can emit infrared light of different frequencies.

[0009] Furthermore, an electromagnet is fixedly provided on the contact surface between the feeding box and the barcode scanning operation module; correspondingly, a soft electromagnet is fixedly provided on the barcode scanning operation module.

[0010] Furthermore, the flip-plate unloading module includes a flip plate, a flip plate shaft, a flip plate frame, a flip plate motor, a flip plate gear, and a flip plate half gear; the flip plate is fixed to the side of the flip plate frame via the flip plate shaft; the flip plate motor and the flip plate gear are fixed inside the flip plate frame; the flip plate half gear is fixed to the back of the flip plate and meshes with the flip plate gear to drive the flip plate to move.

[0011] Furthermore, a shock-absorbing cover plate is riveted to the upper surface of the flap.

[0012] Furthermore, several displacement sensors are fixed inside the feeding box for real-time sensing of whether the position of the confidential carrier in the feeding box has changed.

[0013] Furthermore, the feeding port is a feeding port for feeding a single type of classified carrier; or, the feeding port is a plurality of feeding ports of different widths that are independent of each other and used for feeding different types of classified carriers; correspondingly, a plurality of opposing flip-plate feeding modules are provided at the bottom of the feeding box.

[0014] Furthermore, the scanning module is equipped with a printer interface, a network interface, and a fingerprint module interface.

[0015] Furthermore, the contactless classified carrier security seizure mechanism also includes a control system, which adopts a distributed control method and includes two microprocessors; The microprocessor I controls the barcode scanning module, which is operated in a contactless manner to scan the barcode or QR code on the confidential carrier contained in the feeding box. The microprocessor II controls the flip-board unloading module, human-machine interaction, and the processing of various information to complete the contactless registration and collection of classified carriers.

[0016] Advantages of this invention: 1. This invention enables fully automated, contactless collection of classified materials, effectively reducing the contact range of classified materials, preventing them from being directly touched by others during the collection process, avoiding the risk of being swapped or having classified information stolen after the classified materials are scanned, collected, registered, and confirmed, and improving the security of the entire collection process.

[0017] 2. Because the present invention integrates the scanning module inside the collection mechanism and scans the barcodes or QR codes on the confidential carriers placed in the feeding box and in the enclosed space, the entire process is contactless scanning, which solves the problems of scanning deception and swapping during the collection process and achieves accurate collection.

[0018] 3. This invention incorporates multiple sets of infrared signal receivers inside the material collection bin of the collection mechanism, and multiple sets of infrared light emitters on the barcode scanning module. Based on the timing of the infrared light received by the receivers, it monitors in real time whether classified materials inside the bin have been moved or whether anyone is attempting to remove them. For example, normally, classified materials enter the bin from top to bottom; if someone attempts to remove them, the materials move from bottom to top. In these two scenarios, the timing of the infrared light received by the receivers at the top and bottom of the bin will differ. Upon detecting any anomalies, this invention immediately triggers an alarm, preventing theft or substitution of classified materials after scanning, collection, registration, and confirmation, thus improving the security of the classified material collection process.

[0019] 4. This invention sets up multiple sets of infrared signal receivers in the material feeding box of the collection mechanism and multiple sets of infrared emitting lights on the barcode scanning operation module. The infrared emitting lights emit infrared light of different frequencies and can monitor the closed status and whether the barcode scanning operation module is turned on in real time. This prevents others from trying to take out the confidential carriers in the material feeding box by opening the barcode scanning operation module, ensuring that no one touches the confidential carriers during the entire collection process, improving the security of the entire collection process, and achieving accurate collection.

[0020] In addition, the present invention has an electromagnet installed on the contact surface between the feeding box and the scanning operation module. During the collection process, it ensures that the scanning operation module and the feeding box are tightly connected to form a closed space, so that others cannot access the confidential carrier that has been scanned, collected, registered and confirmed. All acts of illegally opening the feeding box, scanning operation module and moving confidential carrier are monitored, recorded and uploaded, thereby improving the security of the entire collection process.

Detailed Implementation

[0022] The structure and features of the present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that various modifications can be made to the embodiments disclosed herein; therefore, the embodiments disclosed in this specification should not be considered as limitations on the present invention, but merely as examples to make the features of the present invention readily apparent.

[0023] like Figure 1 , Figure 2 As shown, the contactless classified carrier security collection mechanism of the present invention includes a feeding box 1, a barcode scanning operation module 2, and a flip-plate unloading module 3.

[0024] The barcode scanning module 2 is installed in front of the feeding box 1, forming a closed space with the feeding box 1 for containing confidential materials. The barcode scanning module 2 has a built-in movable barcode scanning module, which can be operated without contact to scan the QR code or barcode on the confidential materials in the closed space.

[0025] The flip-plate unloading module 3 is fixed to the bottom of the feeding box 1 and is used to slide the classified carriers that have been scanned and placed in the enclosed space into the collection cabinet below the collection agency.

[0026] like Figure 2 , Figure 3As shown, the feeding box 1 is a front-opening box with a trapezoidal cross-section on one side. The top of the box has a feeding port 11 for classified carriers to pass through. Inside the feeding box, below the feeding port, there is an inwardly recessed cavity 12. When a classified carrier is fed into the feeding port 11, it falls backward into the inwardly recessed cavity 12 under the action of gravity. The purpose of this design is to prevent others from attempting to hook the fed classified carrier out of the feeding port with tools, thereby stealing or switching the classified carrier.

[0027] A barcode scanning module 2 is installed in front of the feeding box 1, and the barcode scanning module 2 is connected to the feeding box 1 via a damping hinge 13. An electromagnet 14 is fixed on the contact surface between the feeding box 1 and the barcode scanning module 2. When the collection mechanism is working, the electromagnet 14 is energized, and the barcode scanning module 2 and the feeding box 1 are attracted to each other, forming a closed space for accommodating classified materials. If a classified material is mistakenly added or needs to be removed, the electromagnet 14 can be de-energized, separating the barcode scanning module 2 from the feeding box 1.

[0028] To further ensure that the scanning operation module 2 and the feeding box 1 are magnetically engaged during the confiscation of classified materials, and that the classified materials are contained within a closed space, this invention installs several sets of infrared receiving diodes 15 at the upper and lower edges of the opening of the feeding box 1. Correspondingly, several infrared light-emitting diodes are installed on the scanning operation module 2. If the feeding box 1 is opened, i.e., the scanning operation module 2 separates from the feeding box 1, the infrared receiving diodes on the feeding box will not receive the infrared light emitted by the infrared light-emitting diodes on the scanning operation module 2, and an alarm will be triggered immediately. In addition, several displacement sensors are also fixed inside the recessed cavity of the feeding box 1 to sense in real time whether the classified materials in the feeding box have changed position, thereby determining whether the movement of the classified materials is normal, to ensure that the classified materials are confiscated in a contactless, fully enclosed space. Suppose someone attempts to remove a classified carrier that has been placed in the feeding box. If the person forcibly opens the barcode scanning module 2 in front of the feeding box, or uses other means to hook the classified carrier out from the feeding port, the infrared receiving diode installed at the opening of the feeding box and the displacement sensor inside the feeding box cavity will both detect the shaking and change in the relative position of the carrier as it moves from bottom to top, thus issuing an alarm signal.

[0029] To facilitate the management of classified materials, barcodes or QR codes indicating their classified information are usually affixed to them. Traditionally, staff use barcode scanners to scan these codes for registration and confiscation. However, in practice, while staff may scan genuine classified materials, the materials placed into the confiscation device are not the scanned ones, but rather other stored media that have been switched. To avoid this, this invention integrates a scanning module within the scanning operation module 2, enabling contactless scanning. Scanning is only performed on classified materials placed in the feeding bin, and no one touches the scanning module or the classified material during the entire process. Furthermore, confiscation is only complete after the scanned classified material falls into the flip-plate feeding module 3. The entire process eliminates direct contact between the scanning module and the classified material, preventing the risk of switching or theft of classified information.

[0030] like Figure 1 , Figure 2 , Figures 4-6 As shown, the barcode scanning module 2 is installed at the opening of the feeding box 1, directly facing the recessed cavity 12 inside the feeding box, allowing direct viewing of the confidential carriers falling into the cavity. The barcode scanning module 2 includes a front cover 21, a resistive screen 22, a support frame 23, a transparent fixing plate 24, a barcode scanning module 27, a stepper motor 25, an X-axis zero-return sensor 29, a Y-axis zero-return sensor 210, an infrared light-emitting diode 211, and an electromagnetic soft iron 212.

[0031] The resistive touchscreen 22 is located between the front cover 21 and the support frame 23. The support frame 23 is fixed to the front cover 21 with screws, thus clamping the resistive touchscreen 22 between the front cover 21 and the support frame 23. A transparent fixing plate 24 is also provided behind the support frame 23, and a stepper motor 25 is fixed on the fixing plate. The stepper motor 25 pulls the barcode scanning module 27 via a traction rope 26. Figure 7 As shown, a traction wheel 28 is fixed to the output shaft of the stepper motor 25, and a traction rope 26 is wound around the traction wheel 28. The holder of the classified carrier, or the director or specialist of the classified information office, determines the position of the barcode on the classified carrier through the resistive touch screen 22. The control system drives the stepper motor 25 to pull the scanning module 27 to move via the traction rope 26 according to the barcode position, scanning the barcode or QR code on the classified carrier. In a preferred embodiment of the present invention, a stepper motor is fixed at each of the four corners of the fixed sealing plate, and the scanning module is connected to the four stepper motors respectively through four traction ropes, and the four stepper motors pull the scanning module to move. Of course, the scanning module can also be driven to move by other driving methods, such as by fixing X-axis and Y-axis slide rods, lead screws, synchronous pulleys, etc. on the fixed sealing plate.

[0032] In order to accurately determine the position reached by the barcode scanning module 27, an X-axis zeroing sensor 29 and a Y-axis zeroing sensor 210 for positioning are fixed on the fixed sealing plate 24.

[0033] In this invention, several infrared light-emitting diodes 211 are fixed at different positions on the fixed sealing plate 24. These work in conjunction with the infrared receiving diodes 15 on the feeding box to sense whether the barcode scanning module 2 is separated from the feeding box 1, and whether the confidential carriers placed in the feeding box have been moved. To prevent others from using an infrared remote control to simulate the infrared light-emitting diodes 211 to remotely control the infrared receiving diodes in the feeding box, the control system of this invention outputs control signals to make the infrared light-emitting diodes 211 emit infrared light of different frequencies.

[0034] An electromagnetic soft iron 212 is also fixed on the fixed sealing plate 24. The electromagnetic soft iron 212 cooperates with the electromagnet 14 on the feeding box to attract the barcode scanning operation module 2 to the feeding box 1, forming a closed space to accommodate the confidential carrier, thereby achieving the purpose of non-contact scanning of barcodes or QR codes on the confidential carrier in a closed state.

[0035] like Figure 2 , Figure 4 , Figure 5 As shown, to improve the overall safety of the barcode scanning module and fix the barcode scanning module 27 in a relatively enclosed space, a back cover 213 is added to the back of the fixing plate. The front cover 21, the support frame 23, and the back cover 213 are combined into an overall frame, which fixes the resistive screen 22, the barcode scanning module 27, the transparent fixing plate 24, the stepper motor 25, the zeroing sensor, and the infrared LED within the overall frame.

[0036] The front cover 21 of the barcode scanning operation module is also equipped with a status indicator light 214 and a buzzer to display the status of the barcode scanning operation module. When the barcode scanning operation module 2 is separated from the feeding box 1 or the confidential carrier in the feeding box is touched by a person, the status indicator light flashes and the buzzer sounds an alarm.

[0037] When it is necessary to remove the confidential carrier from the feeding box for some reason, in order to facilitate the opening of the barcode scanning module 2, the present invention provides a handle 215 on the front cover 21.

[0038] like Figure 6 , Figure 8As shown, the barcode scanning module 27 is a mature module, and the present invention uses a barcode scanning module with a built-in RFID reader / writer. It consists of an upper cover 271, a lower cover 272, a barcode scanning camera 273, a barcode scanning circuit board 274, an infrared emitting light 275, and an RFID reader / writer 276. The upper and lower covers form a closed housing. The barcode scanning camera 273 is fixed to the outer surface of the upper cover and electrically connected to the barcode scanning circuit board 274, which is fixed inside the closed housing. The barcode scanning circuit board 274, the infrared emitting light 275, and the RFID reader / writer 276 are fixed inside the housing.

[0039] like Figure 2 , Figures 9-12 As shown, the flip-plate unloading module 3 includes a flip plate 31, a flip plate rotating shaft 32, a flip plate frame 33, a flip plate motor 34, a flip plate gear 35, a flip plate half gear 37, a buckle plate 38, and a flip plate shock-absorbing pad 39.

[0040] The flip-plate unloading module 3 is located at the bottom of the feeding box 1. When the holder of classified materials or the director or specialist of the classified materials office puts the classified materials into the feeding box 1, the barcode scanning module 2 scans the code, and after the holder of classified materials or the director or specialist of the classified materials office confirms that the classified materials are to be disposed of, the confirmation button is pressed, and the flip-plate 31 of the flip-plate unloading module 3 opens (e.g., Figure 11 As shown), the classified carrier falls into the collection cabinet below the feeding box via the flip-plate unloading module 3, and the flip-plate 31 returns to its original position and closes (as shown). Figure 9 (As shown), the collection process is complete.

[0041] As shown in the figure, the flap 31 is fixed to the side of the flap frame 33 via the flap pivot 32. Before the holder of the classified material determines to send the classified material for disposal, the flap 31 is in a closed state (e.g., ...). Figure 9 As shown), flap 31 blocks the material discharge port of the feeding box; flap 31 is only open when the holder of the classified material determines that the classified material will be sent for disposal (as shown). Figure 11 As shown), the classified carrier is dropped into the collection cabinet below it via the flip-plate unloading module 3.

[0042] As shown in the figure, a flap motor 34 and a flap gear 35 are fixed inside the flap frame 33. The flap motor 34 is fixed inside the flap frame 33 by a fixing plate 36, and the flap gear 35 is connected to the motor output shaft of the flap motor 34.

[0043] The flap half gear 37 is fixed to the back of the flap 31 by the snap-fit ​​plate 38 and meshes with the flap gear 35. The flap motor 34 drives the flap 31 to move through the flap gear 35 and the flap half gear 37.

[0044] To prevent unauthorized personnel from attempting to remove the flap 31 and retrieve classified materials from the confiscation cabinet, this invention includes a shock-absorbing cover 39 riveted to the top of the flap 31. The flap half-gear 37 that drives the flap's movement and the locking plate 38 for fixing are both installed on the back of the flap 31. Once this invention is installed and shipped from the factory, unauthorized personnel cannot easily disassemble the flap 31.

[0045] like Figures 13-15 As shown, for ease of operation, the present invention also installs an independent lifting screen module 4 on the feeding box. The lifting screen module 4 includes a display screen 41, a support base 42, a lifting motor 43, a gear 44, a mounting frame 45, a rack 46, a slide groove 47, and a spring ball 48.

[0046] A support base 42 is fixed to the bottom of the display screen 41, and a lifting motor 43 is fixed on the support base. The output shaft of the lifting motor is connected to a gear 44. A rack 46 meshes with the gear on the mounting frame 45; grooves 47 are provided on both sides of the mounting frame, and spring beads 48 are spaced apart in the grooves. The display screen 41 and its support base 42 are embedded in the mounting frame 45. The display screen 41 is driven to rise and fall by the meshing of the rack and gear and the interaction between the spring beads and the display screen and the support base.

[0047] To prevent unauthorized access to the feeding box 1 by disassembling the lifting screen module 4, the lifting screen module 4 and the feeding box cavity 12 are not connected. A separate inspection door is provided on the back of the feeding box for installing and inspecting the lifting screen module. Figures 1-16 The feeding port of the contactless classified media security collection mechanism shown is for feeding a single type of classified media. For example, a feeding port with a 2 mm gap can only feed paper classified media, or a feeding port with a 28 mm gap can only feed hard disk classified media, or a feeding port with a 3 mm gap can only feed optical disc classified media, or a feeding port with a 10 mm gap can only feed USB flash drive classified media.

[0048] like Figure 17 , Figure 18 As shown, depending on the thickness of the classified medium being inserted, the feeding port of the feeding box can be divided into several independent slits of different widths, such as feeding port 111 for hard drives, feeding port 112 for optical discs and paper media, and feeding port 113 for USB flash drives. Correspondingly, as... Figures 19-22 As shown, corresponding to each feeding port, a flap discharging module is provided at the bottom of the feeding box, such as flap discharging modules 311, 312, and 313. The three flap discharging modules move independently of each other, and their structure is similar to... Figures 9-12 The structure and working principle of the flip-plate unloading module 3 are the same, and will not be described again here.

[0049] like Figure 23 As shown, the control system of this invention adopts a distributed control method and includes two microprocessors. Microprocessor I is mainly responsible for controlling the barcode scanning module to acquire the barcode or QR code of the confidential carrier.

[0050] After the classified carrier is placed into the feeding bin, the holder touches the resistive touchscreen to determine the position of the barcode or QR code on the carrier. Microprocessor I outputs a control signal based on the barcode position to drive a stepper motor, which in turn drives the scanning module to the designated position to scan the barcode or QR code on the classified carrier. After scanning, as needed, microprocessor I uses signals from the X-axis and Y-axis zeroing sensors to drive the stepper motor to pull the scanning module back to the zeroing point. Microprocessor I acquires the barcode, QR code, or RFID information scanned by the scanning module and transmits the information to microprocessor II, which then transmits it to the host computer.

[0051] When the barcode scanning module is working, the microprocessor I outputs a pulse signal, causing the infrared LED to emit infrared light of different frequencies. The infrared receiving diode on the feeding box receives the infrared light and monitors in real time whether the barcode scanning module and the feeding box are engaged and the status of the confidential carrier in the feeding box. The status of the barcode scanning module and the confidential carrier is displayed through status lights. An alarm is triggered when an abnormality occurs.

[0052] The microprocessor II is mainly responsible for controlling the flip-board unloading module, the lifting screen module, human-machine interaction, and the processing of various information, so as to realize the contactless registration and collection of classified carriers.

[0053] Microprocessor II uses infrared receiving diodes on the feeding box to detect in real time whether classified materials are being fed in, whether they have been moved, and whether their status is normal. Upon receiving a signal from microprocessor I confirming completion of scanning and confiscation of the classified materials, it sends a control signal to drive the flip-plate motor of the flip-plate unloading module to open the flip-plate, allowing the classified materials to slide into the confiscation cabinet below the confiscation mechanism. Then, it drives the flip-plate motor to close the flip-plate, completing the confiscation and recording relevant information which is then uploaded to the host computer.

[0054] When the barcode scanning module and the flip-board unloading module are working, the microprocessor II sends a control signal to energize the electromagnet on the feeding box and attract the electromagnet on the barcode scanning module. The barcode scanning module and the feeding box are always kept in a closed state. The microprocessor II monitors the status of the classified carrier in real time through infrared receiving diodes and displacement sensors. It drives the lifting motor to raise the display screen to realize human-machine interaction.

[0055] Microprocessor II also manages the printer interface, fingerprint module interface, and Ethernet interface on the material feeding bin. When there is no barcode or QR code on the classified material, a QR code is generated directly, printed, and affixed to the classified material.

[0056] The present invention can also be connected to an external fingerprint module. The microprocessor II can input the operator's fingerprint through the fingerprint module to complete the authentication of user rights.

[0057] The Microprocessor II can also upload and download data and instructions via an Ethernet interface.

[0058] The following example illustrates the entire process of seizing classified materials: First, the seizure agency is powered on, and the operator (usually the holder of the classified material or the director or specialist of the confidentiality office) verifies their fingerprint. The seizure agency then determines whether the operator has the authority to use the seizure agency. If the operator has the authority, the seizure process begins, and the operator's identity information is registered. When the electromagnet on the feeding box is energized, the feeding box and the barcode scanning module are attracted to each other; the display screen rises and displays relevant information. After logging in and confirming the information, the screen displays that feeding is possible. Take out the prepared classified carrier and check if it has a barcode or QR code. If it does, put it directly into the feeding box. If it does not have a barcode, operate the screen to print the QR code or barcode, print it with the printer, stick it on the front of the classified carrier (try not to stick it too close to the edge), and put it into the feeding box. After the classified carrier is placed into the feeding box, touch the resistive touch screen and gently touch the barcode position on the classified carrier. The barcode scanning module moves to the barcode position according to the touch sensor, identifies and reads the barcode, and uploads the read information. If the identification is successful, it is confirmed that there is no problem. At this point, the display screen shows "Information Confirmation". After successful confirmation, the display screen will ask whether to continue "feeding". If you choose yes, you can continue to feed classified carriers for batch scanning and registration. If you choose no, the flip-plate of the flip-plate feeding module will open automatically, and the successfully scanned classified carriers will enter the collection cabinet below the collection agency. The flip-plate will then reset, and the collection of classified carriers will be completed. The scanning results will be uploaded. If the scanning is unsuccessful, or if you do not wish to continue even though the scanning is complete, you can open the previous scanning operation module, take out the classified media, and assume that the fed classified carriers have not been collected. All relevant data will be uploaded. From the moment the classified carrier is placed into the feeding box, the system will automatically monitor in real time the engagement status between the barcode scanning module and the feeding box, as well as the position and status of the classified carrier. If any abnormality occurs, an alarm will be triggered immediately and abnormal information will be uploaded.

[0059] Because this invention integrates a scanning module and only scans classified materials placed in the feeding bin, and sets up multiple infrared transmitting and receiving devices at different locations in the collection agency to monitor the theft of classified materials, it truly enables the collection agency to directly complete the anti-fraud scanning registration and collection work in a fully enclosed space. This fundamentally eliminates the risk of classified materials being touched by others during the collection process, and avoids the risk of being swapped or having classified information stolen after the classified materials have been scanned, collected, registered, and confirmed.

[0060] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
